Cooee! Sound-testing 1200 metres beneath the waves

We're using an echolocator to watch the daily migration of sea life rise up from depths to feed at dusk and then return back to the depths at dawn. But some fish have oil-filled bladders rather than a gas bladder making their reflection weak and difficult to count. That's where our special camera comes in.

Here’s the seafood Australians eat (and what we should be eating)

Over 85 per cent of seafood caught in Australia is sustainable. However, just because a fish is sustainably caught, it doesn’t make it the most nutritious and healthy option – and vice versa. We've compared the two to see what seafood is both sustainable and nutritious.

Loose genes and haunted ecosystems: meet eDNA, environmental saviour

'Environmental DNA' tells the story of an ecosystem, the genetic signatures of plants, animals, fungi, microbes in a milieu that can be ‘snooped on’ by researchers to detect exotic species and contaminated waterways, and inform palaeoecology and marine conservation.

Love is in the water: Critically endangered handfish embrace art, new ceramic nests

The spotted handfish—the first marine fish to be declared Critically Endangered—is a Tasmanian treasure and we've just paired science with art to help bring them back from the brink.

We came we saw: saving the sawfish

Sawfish are critically endangered. We recently worked with Indigenous rangers to help save these sawsome fish!

Whale, whale, whale, what do we have here?

Scientists on our research vessel Investigator were treated to a spot of whale watching over the weekend.

Plastic is deadly: how you can help

We calculated how many MCGs it would take to hold all the plastic in our oceans. Spoiler alert: a lot. Plastic is filling our oceans, killing animals and costing us billions. We need your help to solve this massive problem so here's what you can do about it.

Warming oceans are changing Australia’s fishing industry

A new United Nations report on fisheries and climate change shows that Australian marine systems are undergoing rapid environmental change, with some of the largest climate-driven changes in the Southern Hemisphere.

The mysterious beast of Ningaloo Reef: revealing the secrets of whale sharks

We’re uncovering the secrets of whale sharks by tracking their movements at Ningaloo Reef.

A helping hand for a unique, spotty Tasmanian

Spotted Handfish may be critically-endangered, but with the help of a captive breeding program their future is looking considerably less murky.

You never know what you’ll find in the Abyss

The depths of the ocean are one of Earth's most inaccessible and unexplored environments, and getting a sneak peek into what lives down there can provide great insight into managing marine diversity.
